"Roseanne" Cancelled Following Star's Racist Tweet

ABC-TV cancelled its hit reboot of "Roseanne," following Barr's racist tweet that referred to an Obama assistant as "a product of the Muslim Brotherhood and "Planet of the Apes" -- "muslim brotherhood & planet of the apes had a baby=vj."

The network in February 1969 acted swiftly cancelling "Turn On," a would-be "Laugh In" spin-off after one episode.
